On my 2021 Porsche Cayenne Base, which is equipped with the 3.0L V6 EA839 engine, I brought the vehicle to the dealership for a recall service. During inspection, the dealership found a leaking water pump and quoted $8,500 for repairs. There were no visible signs of a coolant leak on the ground, indicating an internal seal failure. My independent technician confirmed that coolant is leaking internally into the vacuum system. This EA839 engine architecture is shared across multiple Volkswagen Group models, including Audi A6, A7, A8, Q7, and Q8, where this water pump internal leak is a known, widespread manufacturer defect that has already triggered class action lawsuits.

Battery completely discharged and the safety switch in the battery malfunctions and battery can not be charged again. There are many complaints seen online about the battery problems Porsche has. This strands the car and me the driver. The dealer and independent mechanics said the same. There were no warning lamps or messages prior to the failure.

Vehicle Information: 2021 Porsche Cayenne E-Hybrid (VIN: [XXX]) Description of Defect: While operating the vehicle, the steering column bolt physically backed out and detached, causing an immediate, complete loss of steering control. This exact mechanical failure mirrors NHTSA Safety Recall 21V-493 (Porsche Campaign AMB4), which addressed loose, under-torqued steering column bolts leaving the factory. My specific VIN was excluded from the narrow initial recall population, proving a factory tracking failure by the manufacturer. The authorized Porsche dealership confirmed the failure stating the bolt backed out due to "vibrations." A vital steering bolt backing out under normal road vibrations on a 2021 luxury vehicle is a severe manufacturing defect and a life-threatening public safety hazard. Injuries/Crash: No Fire: No Speed at incident: 25 mph INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Is 21 complaints a lot? They were filed between 2021 and 2026, roughly 4 a year, which is fewer than the typical model in this dataset. We do not have sales figures for this model, so treat this as a rough volume, not a rate per car on the road. Popular, high-volume models naturally collect more complaints over time.

How does it compare with other years? The 2021 has 21 complaints on file, fewer than the 2020 (24). Of the 11 model years of the Porsche Cayenne we cover, the 2014 has the most (53). Older model years have had longer to collect complaints.
